Abstract: This invention relates to a novel guiding method for autonomous traveling vehicle in which the number of the rotation of wheels mounted on both the right and left sides are individually detected when guiding the vehicle along the predetermined route by independently controlling the rotation of the wheels mounted on both the right and left sides, and then based on the number of the rotation of these wheels, the position and the azimuth of the vehicle are computed. Then, based on the computed position and the azimuth of the vehicle by referring to the predetermined route, the target position is set, and then, by the vehicle is made to travel toward the set target position. Setting the target positions and making the vehicle travel toward the target position are repeated so that the autonomous vehicle is guided to the route having been set. When marks are detected during the travel, fixed point correction in reference to the detected marks is executed. Moreover, yawing is corrected when the vehicle is guided to the predetermined route after the fixed point correction.

Abstract: To convert an analog current to a digital signal using a high-speed pipelined analog-to-digigal (A/D) converter, the A/D converter may comprise a current sample- and hold (S/H) circuit at the input and several identical pipelined stages, where each stage contains a current S/H circuit, a current interstage low-resolution A/D converter and current references. To improve the speed of pipelined current-mode A/D converters the capacitive load seen by the output of every stage will be reduced. By adjusting the reference currents the power consumption will also be reduced. It is possible to achieve about 100 Msamples/s conversion rate and to reduce the power consumption by several times compared with existing designs. To increase the operation speed and to provide means to reduce the power consumption the pipelined current-mode A/D converter may comprise an S/H circuit (7) as the input and N pipelined stages (8), each of which contains an internal low-resolution A/D converter (9), a D/A converter (10), an S/H circuit (11), a reference current source (12) and an adder/subtractor (13). The most distinguishing features of the invented architecture are: 1) the inputs to the internal A/D converter and the interstage S/H circuit are timeinterleaved; and 2) the reference current to the D/A converter in every stage can be different.

Title: Process and installation for obtaining of cereals drying agent
Inventor: HĂBĂŞESCU ION
IPC: F26B23/02
Filed: 2000-07-14
Abstract: The invention relates to the agricultural machinery industry, in particular to a process and an installation for obtaining of cereals drying agent.The process includes burning of the liquid fuel and feeding of the combustion products flow from the combustion chamber into the air flow sucked in from the environment by the fan of the chamber for cereals drying and mixing thereof. The air flow sucked in by the fan is formed of two parts. A part of the air is sucked in by the fan directly from the environment. The second part of the air is infiltrated from the environment through the reception confuser of the housing and the annular clearance formed between the combustion chamber and the housing. At the same time, the second part of the sucked in air cools the combustion chamber and it is compressed at the outlet of the housing confuser, forming a flow of combustion products enveloped by compressed air, which is fed through the open air annular clearance in the fan, where it is mixed with the first part of the sucked in air.The installation for realization of the process contains a fan for air suction from the environment, a straight-flow combustion chamber with burner and a housing. The combustion chamber has its back end open for the outlet of the combustion products flow and it is installed into the frame, providing the possibility of displacement about the fan. Between the housing and the combustion chamber it is formed an air annular clearance. The combustion chamber is provided with a screen and a confuser, and the housing is provided with inlet and outlet confusers.The result of the invention consists in reducing the pressure loss of the combustion products and sucked in air, in increasing the purity of the fed drying agent, increasing the reliability of the installation and in the possibility of regulating the clearance between the combustion chamber and the fan.
